T0 al?, whom it may concern:

Be it known that I, BARDEN WAL'roN TAY- LOR, a citizen of the United States, and a resident of the cityofNew York, borough of Manhattan, in the county and State of New York, haveinvented a new and Improved Steam and Heat Oonservator, of which the following is a full, clear, and exact description.

The invention relates to steam apparatus; and one object is to condense the exhaust or Waste steam and utilize the heat of such steam for reheating and su perheating the water of condensation and for heating air 'to be used in the fire-box to insure acomplete combustion of the fuel in the furnace.

A further object of the invention is to purify the water of condensation and form feed-water free from all foreign matter liable to produce scale in the boiler or incrustation therein or foam from oil.

In addition to the advantages enumerated others are contemplated and will appear to those skilled 'in the art as the invention is comprehended. j

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafterand then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate co1'.- responding parts in all the views.

Figure l is a perspective view of the improvement. Fig. 2is alongitudinal sectional rear elevation of the sameon the line 2 2 in Fig. 3. Fig. 3 is a sectional plan view of the same on the line 3 3 in Fig. 2, and Fig. 4 is an enlarged elevation with parts in section of a modified form of the condenser for the exhaust-steam.

Theimproved apparatus shown in the drawings appears in the shape of an oblong box made in sections fastened together by suitable means, and the box is divided, essen! tially, into a central steam-condensing and air-heating compartment A, over which is located a settling-chamber B and below which is arranged a feed-water tank C. The exhaust-steam fromthe engine, mot-or, or other 1900. Serial No. 17,684. (No model.)

steam apparatus passes into one end of the condensing and heating chamber through an inlet-pipe D, and this steam is wholly or partly condensed in the said compartment, and any steam not condensed in the compartment is carried off therefrom by an outlet-pipe D', rising from the other end of said compartment.

In the compartment A are arranged baffleplates E E', of which the baftle-plates E,rise from the bottom of the compartment A to within a distance of the top of said compartment, while the other bafefplates E depend from the top of the compartment A to wit-hin adistance of the bottom thereof, so that the steamer-.tering the compartment A at one end travels'in a tortuous route through the compartment before reaching the outlet-pipe D'.

As shown in Fig.- 2, the top ofthe compartment A forms the bottom of the settling-chamber B, and the bottom of said compartment A forms the top of the feed-water tank C, so that the steam in its passage through thecompartment A gives od units of heat to the said chamber B and the tank O.

In the compartment A are arranged banks of coils F, each opening at one end into an air-distributing chamber G, connected with the discharge-pipe H of a fan H, of any approved construction, used for forcing air into said distributing-chamber Gr, from which the air can pass through the several banks of coils F and finally pass through the other ends of said banks of coils into a receiver I, connected by a pipe I' with the furnace used for generating steam to assist in the complete combustion of the fuel employed in said furnace. Now it is evident that air traveling through the coils F takes up heat from the exhaust-steam traveling in a circuitous route through the compartment A and around said coils, the travel of the air being in an opposite direction to that of the stealn, so that air passing through the coils F is gradually heated, as it is first subjected to steam of a low tem perature and gradually s u bj ected to steam of a higher temperature until it leaves the coils and passes into the receiver I, at which point the coils are subjected to the higher heat of the entering Waste or exhaust steam,

Vas Willbe readily understood by reference to IOO Fig. 2. As the exhaust or waste steam passes from the comparatively small pipe D into the large compartment A, open to the atmosphere at the pipe D', it is evident that the said steam is free to expand in the compartment, thus relieving the engine of back pressure.

From the foregoing it is evident that the temperature of the exhaust-steam in the coinpartment-Ais lowered by the transfer of heat units to the air, and this lowering of temperature insures condensation of the steam and the formation of water of condensation accumulating in the bottom of the compartment A. The heated air transfers the heat units to the furnace for reuse in the generation of steam, the degree of heat being indicated by a thermometer I2, arranged on the pipe I', as indicated in Figs. 1 and 2. The heated air, besides serving as a medium to transfer the heat of the steam back to the furnace, has the additional function of supplying highly-heated oxygen to the furnace to insure a complete combustion of the fuel and to avoid the formation of smoke and the escape of unconsumed gases. In order to increase the eflciency of this air as an aid for complete combustion, it may be charged with exhaust-steam, and for this purpose the inlet-pipe D is connected by a pipe D2 with the receiverl to conduct steam from said pipe D to the receiver for the steam to mix with the highly-heated air, the mixture 'passing into the fire-box of the furnace for the purpose mentioned. The amount of steam admitted to the receiver is regulated by a valve D2 in the pipe D2.

The baffle-plates E' in the compartment A are either perforated at the lower ends or set slightly above the bottom of the compartment to permit the water of condensation to readily flow at one end to a pipe J, which delivers the water of condensation into a separator K, used for freeing the water from oil, scum, and other floating matter previous to passing the water to the tank C by way of an opening C', arranged in the separating-plate between the separator K and the tank O. (See Fig. 2.) Into the separator K is also passed heated and purified water necessary to make up the deficiency of water in filling the boiler, and this water is passed into the separator K by a pipe B from the settling-chamber B, hereinafter more fully described in its detail construction. Thus the water of condensation and the fresh water are mixed in the separator and pass from the latter into the tank C, which in turn is connected by a pipe L' with a feed-water pump L, having its dischargepipe L2 terminating in a coil L2, located in the bottom of the central compartment A, the end of the coil being connected by a feed-waterdelivery pipe L4 with the boiler. A thermometer L5 on the said pipe L4 indicates the temperature of the feed-water as itleaves the apparatus and passes into the boiler. The waste or exhaust steam from the pump L passes by a pipe L'"l into the compartment A, adjacent to the entrance of the exhaust-steam from the pipe D to be treated in the compartment A, as above described.

The pipe J, previously mentioned and used for conducting the water of condensation into the separator K, is formed at its lower end with a perforated discharge-pipe J', extending over the bottom of the separator K, so that the Water of condensation is uniformly distributed in the separator. From the latter leads a blow-olf valve K' for removing the oil, scum, or other foreign matter Iioating on the top of the water in the separator K. A ilo-at K2 rises and falls with the water in the separator, and this fioat is provided with a stem K3, extending through the top of the separator K to connect at its upper end with an arm N on a valve N2, arranged in a feedwater-supply pipe N, discharging by a perforated pipe Nis into the bottom of the settlingchamber B, near one end thereof, as is plainly indicated in Fig. 2. Now by the use of the float K2 the amount of feed-water admitted to the settling-cham ber B is regulated according to the amount of feed-water forced by the pump L back into the boiler, the level of the water in the tank C being at a uniform height at all times, as will be readily understood by reference to Fig. 2.

The perforations in the pipe N3 are in the lower portion thereof to direct the feed-water against the highly-heated lop of the compartment C. lhe settling-chamber B is provided with a number of transverse partitions B2 B3 for forming settling-basins B4 B5 B5, located one alongside the other and in communication .with each other through apertures B7 B5 in the upper parts of the partitions B2 B3. The feed-water from the pipe N passes into the basin B4 and is then by its own gravity transferred to the basin B5 by a pipe O, extending from one end of the said basin B4 outside of the box and terminating in a coil O', arranged in the upper portion of the compartment A, the end of the coil opening into the bottom of the basin B5. rlhe water accumulating in the basin B5 overfiows through the aperture B8 into the basin B5, from which the water finally passes by the pipe B' into t-he separator K. The apertures B7 B8 permit any steam that may arise in the settling-chamber B to pass to the basin B5, from which the steam may escape into a discharge-pipe B9, which also connects With the upper portion of the feed-water tank C to carry olf any steam that may rise therein. The stem K3 of the oat K2 is also connected with an arm O2 on the stem of the valve O3 in the pipe O. The p ipe O is also connected on opposite sides of the valve O3 by drain-pipes P P' with a pipe P2, opening into the top of the separator K, and in said pipe P2 is a valve P3 for controlling the amount of water passing to the separator K by Way of the pipes P P' P2. The valve Ps is normally closed, and when it is de- IIO IIS

sired to drain' the basins B4 and B5 the said valve is opened to allow the water to flow from the basins to the separator. A drain-cock P4 leads from the bottom of the tank C to drain the latter whenever it is desired to empty the apparatus.

The settling-chamber B and the feed-water tank C are provided with suitable water-gages Q', as shown in Fig. 1, to indicate the le\ el ot` the water in said chambers. Suitable manholes Q are provided for the water-tan k C and for the separator K. (See Figs. l and As previously mentioned, the steam finally leaving the compartment A by Way of the pipe D' may be exhausted into the outer air or it may be condensed in a supplementary or auxiliary condenser. (Shown in detail in Fig. 4.) For this purpose the upper end of the pipe D' is provided With a socket D4, in which is mounted to turn a tube R, carrying a head R', from which extend radially a plurality of tubes S and also a vertically-disposed pipe T, formed at its upper end with a head T', from which radiate a number of tubes S',connected at their outer ends with the tubes S by pipes S2, the said tubes S and S' being also connected with each other throughout their length by branch pipes S2, as is plainly indicated in said Fig. 4. .On the top of the tubes S' and near the ends thereof are arranged steam-discharge pipes or valved nozzles U, standing at an angle to the tubes S', so that reaction of the escape of the steam from the nozzles U causes a turning of the several parts enumerated in the Socket D4, Whereby the several pipes S2 S2, together with the tubes S S', are rapidly carried through the air to insure a rapid condensation of the steam passing through the same. S' are also provided with outlet-openings S4 for the free escape of the steam. '[hewater of condensation flows down the several pipes into the tubes S and to the bead R.' and tube R around a pipe D5, forming an extension of the pipe D' within the latter, the upper end of said pipe D5 reaching a distance up into the head R', as is plainly indicated in Fig. 4.

A collar D6 supports the extension-pipe D5 Within the pipe D', and from the latter leads a Siphon-pipe W directly above the said collar to discharge into a Water-receptacle X. A branch pipe W' connects the short and long leg of the Siphon-pipe W, and in this branch pipe is arranged a valve W2, which Iwhen closed causes the water to be siphoned through the pipe W and when open, which is necessary in cold weather, causes a direct iow of water without the siphoning action. A suitable governor Vis employed for the rotating part of the auxiliary condenser to insure uniformity in the speed of said condenser. An air-vent R2 is arrangedin the tube R.

When the apparatus is in use, the exhauststeam entering the central compartment A and traveling through the tortuous passage formed by the baffle-plates E E' readily gives off its heat to the air passing through the The tubes banks of coils F, also to the water passing through the coils O' and L2, as well as to the water in the settling-chamber B and that in the tank C, so that the said steam readily condenses. As the heat. given oit by the exhaust-steam is all utilized, or, in fact, returned to the boiler, partly by the heated feed-Water and partly by the air used for insuring a complete combustion of the fuel in the boilerfurnace, it is evident that with my improved apparatus a great saving in the expense of generating and utilizing steam is obtained.

Itisfurther evident that by the preliminary heating of the feedwater in the settlingchamber B by the heat of the exhaust-steam in the compartment A, located below the chamber, and by the heating of the water in the coil O' a quick precipitation of foreign undesirable matter contained in the feed- Water is obtained, and the feed-water is thus purified to prevent the formation o-f scale in the boiler Without the use of chemicals. As the oil, scum, and other matter contained in the exhaust or waste steam is removed from the feed-water in the separator K, there is no danger of the formation of foam.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
